actully, there is a more simple reproduce script:
<?php
$s = "æ´ªä»";
var_dump(mb_convert_encoding($s, "utf8", "gbk"));
?>
save script in fenc=cp936
than, in php 5.4 this result a :
string(3) "æ´ª"
characters lost while converting from cp936 to utf8. this is really a big
problem.....

seems the characters is lost in the mbfl_buffer_converter_feed2 (called in
zend_multibyte_encoding_converter)

the same script as above, will trigger a abort in this way:
$php54 -d mbstring.internal_encoding=cp936 /tmp/1.php
php: Zend/zend_language_scanner.l:126: encoding_filter_script_to_internal:
Assertion `internal_encoding &&
zend_multibyte_check_lexer_compatibility(internal_encoding)' failed.
Aborted (core dumped)

if I change the script to:
<?php
declare(encoding="gb2312");
$s = "æ´ªä»ç";
var_dump($s);
?>
also set fenc=cp936, then a memory leak will be reported:
$ php54 -d mbstring.internal_encoding=utf8 -dzend.script_encoding=cp936
/tmp/1.php
string(7) "洪�"
